REINFORCED CONCRETE STRUCTURE.

Specification of Letters Patent.

Patented Nov. 8, 1910.

T 0 all whom "it may concern:

Be it known that we, HERBERT E. VI-UTE, of Youngstown, Mahoning county,Ohio, and WILLIAM I'L-IIAM, of New York, county and State of New York,have invented a new and Improved Reinforced Concrete Structure, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawing, forming part of this specification, inwhich- Figure 1 is a partial top plan View, showing one form of ourimproved beam and girder connections; Figs. 2 and 3 are partlal crosssections of Fig. 1, the two sections being taken at right angles to eachother; Figs. 4, 5 and 6 are plan viewsshowing other forms of theconnection: Figs. 7 and 8 show different forms of connecting links oreyebars; and Fig. 9 shows another modification of the connection.

Our invention relates to reinforced concrete beam and girderconstruction; and

particularly to the inter-connecting of the ends of reinforces in suchstructures, and also their connection with the vertical reinforcingmembers of columns or posts of the structure. v

. Heretofore the ends of such reinforces in beams or girders haveusually been extended and embedded in the cement or concrete. Thisnecessitates a considerable extension of the reinforce, or a. memberthereof, and it therewith.

Our invention provides for mechanically connecting the adjacent ends ofbeams or girders, especially those meeting at a vertical column. It alsoprovides for mechanically connecting the end or ends of such reinforceswith a Vertical reinforcing member or members of the vertical column;and also for inter-connecting the ends of beamsor girders where severalof such ends meet at a vertical column.

In the drawing, referring to the form of Fi' s. 1, 2 and 3, 2, 2 and 3,3 represent the ends of reinforcing members of beams extending endwisein line with each other. lVe have shown these reinforcing members aseach consisting of a rod which is bent back-.

forces of beams or girders, these being shown as three in number to eachgirder, whereas the beam reinforces are shown as two in number. Thenumber and form, however, of these reinforces may be varied without de-The girder reinforces may be of the same shape and arrangement as thebeam reinforces,- the bent-back ends of these reinforces terminatingeither at a vertical column or intermediate of the columns.

The reinforces 2 and 3 are mechanically connected together by links oreye-bars 6 and pins 7. These links or eye-bars are preferably bentupwardly, as shown, to allow for the passage under them of the links oreye bars 8, which, together with the pins or bolts 9, connect themembers 4 and 5 of the girders. The cross-sectional detail of Figs. 2and 3 clearly illustrate the manner in which the links or eye-barsextend over and under each other, so that these crossing eye-barsconnect the four ends of the beam or girder reinforces.

In Fig. .4 we show four reinforced beams having reinforcing members 12an l.13 connected by the links or eye-bars. 14 and 15. These eye-barsare secured by bolts 16 and 17 and the eye-bars 15 extend over theeyebars 14, as in the previous form.

In Fig. 5 we show a form similar to that of Fig. 4, in which similarparts are marked with similar numerals, with the letter a applied; butin this case the reinforcing members 12 and 13 are not only connected toeach other by the links 14 and 15, butare also connected to reinforcingmembers 18 of the vertical concrete column, at which the horizontalreinforces meet. These vertical reinforces of the vertical concretecolumn are here shown as rolled angles; but they may be of any desiredform or shape and may be continuous o'r intermittent along the verticalcolumn. VVe' have shown these angles as secured to the horizontalreinforcing members by the same bolts 16. and 17 which connect the links14 and 15. It will, of course, be understood that the number ofreinforces 12 and 13 may be varied, as well as their shape and form,within the scope of this invention.

The angles 18 or their equivalent may be used to connect the reinforcesat the adjacent ends of beams or girders extending at in the outercornersbetween the beam or girder reinforced, the inner angle beingspaced apart from the outer by the ends of the outer reinforcingmembers. both of these angle reinforces for the vertical column may beintermittent or continuous in form.

It will be understood that in any of the forms Where vertical reinforcesare used, such vertical-reinforce may be of any desired form or shapeand may be continuous or intermittent; also that as many verticalreinforces may be usedas desired, in the column. I

In Fig. 7 the link 21 is made in the form of. a chain link with the legsbent toward each other in the intermediate. part, so as to clear thelegs of the crossing link. ()ne link may be bent in one direction andthe corresponding bar of the other link bent in the other direction. e I

In the form of Fig. 8, 'each,eye-bar 21 has a notch-to fit into acorresponding notch in the crossing eye-bar 25. Many other forms ofconnecting links or eye-bars may be empltiyed Within the scope of ourinvention.

11 Fig. 9 we show another form of the invention wherein theupwardly;inclined'member 2 of the reinforce terminates in an eye 26 atits upper end. In this case the connect- 'ing;link 6 is in the form of abar having 'eyes to receive the pins 7 and provided with extensions 27which are embedded in the concrete. In this form, therefore, instead ofbending back and extending the upper members of the reinforce, they aresimply connected to the link or eye-bar, which in turn is extendedwithin the beams orgirders.

The advantages of our invention will be ap arent to those skilled in theart.

secure connection is made at the vertical column between the ends ofthree or more beams or girders, this connection being a mechanicalconnection between the reinforces, and hence affording a secure andpermanent joint. The connecting of the horizontal reinforcing members tothe vertical reinforcing member or members of the column adds strengthand stability, and the staggering'jof the connecting links or mem- Ibers betyve'en ends of the reinforces enables the ends of three or morebeams to be mechanically connected. It will be noted Either or that theconnecting pins, where these are used, are in the same plane, althoughthe links or cross bars are deflected or bent to allow them to pass eachother. This permits of a very simple and eflicient method of directlyconnecting the horizontal members of the floor structure with eachother, and also connecting them with the vertical members j of thecolumn structure, to transfer the strains from the reinforcing membersof the floor to the upright, reinforcing members of the column. Thereinforce of the girder.

or beam may be provided with an aperture 1 for receiving the pin, eltherby punching or I drilling or otherwise forming a hole there m, or bybending back the member, as shown in the drawing. i

By using connectors such as described, a maximum strength is obtainedwith a mlnimum amount of metal. Moreover, by the use of theseintermediate connectors the parts may be made tight so that strains willbe connnunicated from one-reinforce to the other without lost motionwhich would tend to crack the concrete or lnclosing substance. By theword concrete in the cla ms, we

understand to cover any plastic composition of a cementitious or similarnature.

' Our invention is not restricted, -1n lts broader application, to the101111Ilg of beams and girders at the supporting columns. The

union of girders and beams can be arranged v1n the spaces lntermedlatebetween the supporting columns to provide a continuous l beam or girderfrom one side of the bu lding to the other. Where the connection made atthe columns, a connection may or may not be used between the horizontalreinforces and those of the vertical columns.

Many changes may be made in the form and arran ement of the reinforcingmembers, the co umns, the connections, etc., with out departing from ourinvention.
